BrushCAST® Copper Beryllium Casting Alloys - Materion

BrushCAST® Copper Beryllium Casting AlloysThe extraordinary manufacturing and performance characteristics of Materion Brush Performance Alloys BrushCAST CopperBeryllium Casting Alloys offer significant advantages in demanding commercial, industrial, and aerospace component applications.Materion Brush Performance Alloys BrushCAST family of casting alloys offers component design engineers a broad range of materialsolutions that meet the quality, reliability, and high technology requirements of today’s global marketplace.The unique combination of physical and mechanical properties of copper beryllium casting alloys provide a dynamic range ofmetallurgical alternatives to meet specific performance requirements. The inherent strength, hardness, conductivity, and castability ofthese materials make them ideal for applications which require a high performance engineered material solution. Advancements incomponent casting technology and proprietary material production technology pioneered by Materion Brush Performance Alloyshave resulted in BrushCAST alloys being a cost effective design choice.BrushCAST alloys are available in precise measurement, easy to use shot. BrushCAST master alloy and cast billetare also available.High Strength Casting Alloys: 275C, 165C, 21C, and 20CBrushCAST high strength casting alloys provide peak strength and hardness greater than many steels, but with thermal conductivitysimilar to that of aluminum and up to five times that of steel. Additionally, these alloys offer good electrical conductivity, excellentwear and galling resistance, and the highest accuracy in replicating fine detail in cast componentsHigh Conductivity Casting Alloy: 3CAlloy 3C offers excellent electrical and thermal conductivity, good strength & galling resistance, and accurate replication ofcomponent detail. Alloy 3C offers nearly 3 times the conductivity of the high strength alloys, twice the thermal conductivity ofaluminum alloys, and ten times that of steel.Fine Grain Casting Alloys: 275CT, 165CT, and 20CTBrushCAST high strength casting alloys are available in fine grain equivalents. Material properties and manufacturing characteristicsare similar to those of the standard casting alloys. Grain refinement is achieved through precise additions of either cobalt ortitanium. Our fine grain casting alloys are preferred in applications where excellent surface finish characteristics are required in thecast product.Table 1: BrushCAST Copper Beryllium Casting Alloy Physical PropertiesBrushCASTAlloyUNSNo.DensityElastic Moduluslb/in 3 g/cm 3 10 6 psi GPaAverage Coefficient ofThermal Expansionin/in/°F(70-400°F)m/m/°C(20-200°C)ThermalConductivityat 70°F /20°CBTU/W/m°C(ft•hr•°F)ElectricalConductivity% IACS3C C82200 .319 8.83 20 140 10 x 10 -6 18 x 10 -6 144 250 45-50165C, 165CT C82400 .304 8.41 19 130 10 x 10 -6 18 x 10 -6 58 58 20-2520C, 20CT C82500 .300 8.30 19 130 10 x 10 -6 18 x 10 -6 56 56 18-2521C C82510 .300 8.30 19 130 10 x 10 -6 18 x 10 -6 56 56 18-25275C, 275CT C82800 .294 8.14 19 130 10 x 10 -6 18 x 10 -6 52 52 17-23Materion Brush Performance Alloys MATERION CORPORATION AD0092_05136070 Parkland Boulevard www.materion.com/alloys © 2013 Materion Brush Inc.Mayfield Heights, OH 44124 USABrushCast® is a registered trademark of Materion Brush Inc.phone: 216.486.4200 fax: 216.383.4005email: BrushAlloys-info@materion.com
